There are two problems, exposed by existing tests:
- We do not send Page.startScreeencast before Runtime.runIfWaitingForDebugger
because we launch video recorder in between. This stalls when the page is busy
immediately after resuming, e.g. with alert().
Fixed by starting video recorder in advance.
- We wait for the first frame that may not come - for example, context-wide interception
is blocking essential resource and first frame.
Fixed by only waiting for the first frame before reporting the video, not the page.
For some reason typescript can't find electron types when using
nested tsconfig - workaround the bug.
Drive-by: surface installer compilation problems.
Browser registry is responsible for 3 things:
1. Remove downloaded browsers if there are no packages that refer to them
2. Install default browsers needed for the current package
3. Install browsers on-demand when used through Playwright CLI
Currently, registry relies on a single "download" field in `browsers.json`
to carry both (1) and (2). However, browsers in (3) are marked as
`download: false` so that they aren't installed automatically in (2), so
auto-remove procedure in (1) removes them on subsequent installation.
One possible approach to fix this would be modifying package's `browsers.json` to
change `download: false` to `true` when browsers are installed with
Playwright CLI. This approach was explored here:
bc04a51800
We decided against this since we have a history of issues related to
package modifications after NPM installation. This breaks all
sorts of yarn/npm caching mechanisms.
Instead, this patch is a two-step refactor:
- remove the "download" field in `browsers.json`. Now, all registries
(including old ones from previously-released versions) will retain any
browsers that are mentioned in the `browsers.json`.
- add a new flag "installByDefault", that is **only used** for default
installation.
With this change, the registry tasks are done like this:
- (1) auto-removal: if browser has a back reference, it is retained,
otherwise it is removed from registry
- (2) default installation: use only `installByDefault` to carry default installations
- (3) CLI installation: simply installs browsers. Since we retain
everythings that's referenced in (1), browsers aren't removed.
Fixes#5902
This patch rolls Firefox to r1237. Upstream firefox still struggles
with crashes with certain videos: https://bugzilla.mozilla.org/show_bug.cgi?id=1697004
This PR also workarounds this crash by disabling webrender.

This change turns quoted match to be case-sensitive (as before),
but not strictly full-string for the whole element's text.
This is a fix for a case where element contains text nodes and child elements:
```html
<div>text1<span>child node</span>text2</div>
```
We now match this div by `text="text1"` and `text="text2"`.
Cookies have a "Secure" attribute which tells the browsers
that a given cookie should only be sent via HTTPS. In it's
absense "Secure" is falsy and these cookies should be sent
with both HTTP and HTTPS requests. Playwright now returns
only the "Non-Secure" cookies for HTTP URLs, and both
"Secure" and "Non-Secure" cookies for HTTPS URLs.
Fixes#5504
- List all actions we are interested in
- Fix timeline hover flicker
- Extract tabbed pane component
- Preview snapshots without clicking on the action
We might not ever get the "download finished" event when closing the context:
- in Chromium, for any ongoing download;
- in all browsers, for failed downloads.
This should not prevent closing the context. Instead of waiting for the
download and then deleting it, we force delete it immediately and reject
any promises waiting for the download completion.
We get relative registry path when PLAYWRIGHT_BROWSERS_PATH or HOME is relative.
In this case, it would be good to resolve to the same absolute path
during installation and execution, and we can usually do that using INIT_CWD.
- Introduce internal "out of process" start()/stop() mode.
- This mode is used both in regular tests and installation tests.
- Emulate basic driver installation, browser download and running.
- Remove label retargeting, as it does not play nicely with recorder.
- nth-match() is now correctly chained.
- Performance improvements around parent selectors and regex text matches.
- Do not check children when parent does not contain the text we look for.
- Minor caching improvements in evaluator.
This gives up to 5X performance boost on text-heavy pages.
- Snap to buttons, inputs, selects, etc.
- Try `<label>` selector in addition to the element.
- Use parent selectors when needed.
- Remove xpath fallback as it should be covered with css.
Consider the following situation (one among many possible).
- FrameA has an oopif child FrameB;
- FrameA navigates to same-process origin (e.g. about:blank);
- at the same time, FrameC is attached to the FrameB in the
FrameB's process.
In this case, we get `frameNavigated` event for FrameA, immediately
followed by `frameAttached` event for FrameC. Since we detach all
FrameA's child frames on navigation, including the oopif FrameB,
there is no parent frame for FrameC to attach to.
In general, multiple processes coming from oopif may send their
events in wildly different order, and their view about the frame
tree may not always correspond to the "up to date" frame tree as
seen from the main frame's process. We try to keep our frame tree
aligned with what main process thinks, and ignore events that
reference frames absent in this tree.
Drive-by: handle filechooser exceptions because of async processing.
This changes `text=` and `:text()` selectors to match the element when:
- it's combined text content matches the text;
- combined text content of any immediate child does not match the text.
This allows the following markup to match "Some bold and italics text":
`<div>Some <b>bold</b> and <i>italics</i> text</div>`.
For the reference, "combined text content" is almost equal to `element.textContent`,
but with some changes like using value of `<input type=button>` or ignoring `<head>`.
This also includes some caching optimizations, meaningful in complex matches
that involve multiple calls to the text engine.
Performance changes (measured on large page with ~25000 elements):
- `:has-text()` - 14% faster.
- `text=` - 50% faster.
- `:text()` - 0-35% slower.
- `:text-matches()` - 28% slower.
This makes dialogs disappear and prevents stalling.
Pros:
- No need to worry about dialogs for most users.
- Those that wait for a specific dialog still get to control it.
Cons:
- Those who use Playwright to show interactive browser will have
to add an empty 'dialog' handler to prevent auto-dismiss.
We do this in cli.
This patch starts downloading FFMPEG like we download our browsers
instead of bundling it in the NPM package.
With this patch, NPM size is reduced from 8.8MB to 1.7MB.
Consequences:
- `npx playwright` is drastically faster now
- playwright driver for language bindings is way smaller
- projects that bundle Playwright can pass Apple Notorization
Fixes#5193
- We don't need this, since it should propagate from the main frame.
- Forcing focus in oopif immediately focuses it and blurs currently
focused frame. This leads to undesired side effects, e.g. selects
being closed.
This switches vp8 to "realtime" mode that works fast, adapting to
the speed of incoming frames, and produces the best quality in can
given realtime constraints.
In practice, this gives 2x larger video files but no noticible quality
difference. It also eliminates huge delays for encoding the video.
Drive-by: document our ffmpeg option choices and add some links
to documentation for future use.
This fix restores the ability to display images in the Network Tab inside Trace Viewer. Previously data returned from the server was coming back as base64 encoded string, but now it is returned as a Buffer object. This required convertion to either base64 encoded string or utf8 encoded string on the frontend.
